Hi, any help gratefully received.

Brand new PC, connects to wifi for some minutes but then yellow error appears on wifi signal and connection is dropped.

PC Specs:

OS: Windows 10 Pro
Version: 10.0.17134 Build 17134
System type:x64 based PC
System SKU: Default string
Processor: Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz, 3192 Mhz, 6 Core(s), 12 Logical Processor(s)
Installed Ram: 16GB

100% not a problem with the network itself as other devices working fine.

The windows troubleshooter fixes this by resetting the wifi adapter and shows that the issue is related to the default gateway.

However, the fix is always temporary, i.e. a couple of minutes.

Following instructions online I have already:

- Restarted router and pc several times
- Changed channel and frequency on router
- Changed power management of network adapter
- Turned off antivirus
- Checked for Windows upate
- Checked for driver update for network adapter
- Manually setting IP and DNS
- reset ip, flush dns etc.
- Full network reset

The last time it dropped out it generated the following diagnostic information. I'm getting very frustrated... please help!

Are you obtaining an IP address for the device manuall or is it configured to use DHCP? I would always suggest sticking with DHCP, rather than specifying an IP, DNS, etc... manually.

I would also suggest uninstalling the network adaptor driver from device manager, reboot and let it get detected again. I've had this sort of problem a few years ago in Windows 8 and I couldn't get to the bottom of it, but this fixed it - presumably by resetting a problematic config option that I'd missed.

A yellow triangle on the Wi-Fi icon usually means the Internet is not available but your local network is. You might look at your DNS configuration.

You included quite a bit of information in your post but did not show your network connection specifics. I don't still have any systems with an 802.11n adapter but I will check for a Realtek wireless device to see what .inf file it uses to compare whit what you are showing.

Just tried this and no success unfortunately. Starts up working fine... after about 3 minutes same problem once again

Is this brand new PC one that you built yourself, or did you buy one off the shelf?

I'd be tempted to see how the Wifi works when connecting to a different SSID and how it works when booting from a Linux Live CD (perhaps try Ubuntu Live from a USB drive: https://tutorials.ubuntu.com/tutorial/tutorial-create-a-usb-stick-on-windows#0).
Thanks for the reply. The PC was bought online. This Ubuntu approach is new ground for me, so it'll take me a few days, but I'll give it a go.

Good luck - just let me know if you need any help with that part. It'll be interesting to see if it works in Ubuntu, as if it works fine there then it could just be a driver issue. If it was bought online and it fails in Ubuntu, I'd see if they'll send you a replacement WiFi card (a newer one, as that model is quite old).

To all who gave advice,

Thanks for taking the time to reply.

Following the advice, it appears to be a problem with the adapter, I've contacted the seller and in the mean time am using a ethernet cable... faster than the wifi anyway!

Once again, thank you.

Glad you've got this sorted :). Hopefully the replacement adapter won't take too long to arrive :).
